Retired Group One winner Hucklebuck has been put down after suffering a bout of colic.
Prepared by premier Adelaide trainer Phillip Stokes to win eight of his 20 starts including the 2014 Emirates Stakes at Flemington, the six-year-old was retired after an unplaced finish in the Schillaci Stakes in October.
He was the 2015 South Australian Horse of the Year and earned more than A$1.1 million.
Dominic Tourneur, who rode him 18 times, said on Twitter he was devastated.
